目的为了解决医院人工看护成本高、医疗器械监护接线繁多等缺点,设计了基于Zig Bee无线传感网络的光电脉搏心率监测系统。方法该系统以Zig Bee无线传感网络作为通信载体,以自组网的方式监控无线网络节点。系统终端节点监测病人的心率等生命体征数据,通过路由节点将心率数据逐级转发至监控中心。监控中心节点汇总并保存监测数据。结果完成了无线传感网络中各节点的软硬件设计以及监护中心上位机软件设计。结论经实验调试该监护系统能达到设计预期效果,并且具有低成本、易于维护、工作稳定等特点。
Objective In order to solve the shortcomings of the high cost of artificial care in hospitals and the extensive wiring of medical equipment, a photoelectric pulse heart rate monitoring system based on Zig Bee wireless sensor network was designed. Methods The system uses Zig Bee wireless sensor network as a communication carrier and monitors the wireless network nodes by way of ad hoc network. The system terminal node monitors the patient’s heart rate and other vital signs data, and then forwards the heart rate data to the monitoring center step by step through the routing node. Monitoring Center node summary and save the monitoring data. Results The software and hardware design of each node in wireless sensor network and the software design of host computer in the monitoring center were completed. CONCLUSION: The monitoring system can achieve the desired design effect by experiment and has the characteristics of low cost, easy maintenance, and stable operation.
